These filters are a great replacement for the Shark filters that came with my HV382. They fit perfectly and cost a lot more than the filters Shark sells. At first I was concerned that the filters offered were not the same as those on my HV382. I worked with GreenVacShop and we noticed that Shark redesigned the filters in the HV382 but did not provide updated documentation. Now they have made redesigned filters available and they are great.
